MIDI Implementation
●
Program Change
Parameters on the Mixer/Effect section can be changed when UTILITY-MIDI screens
EFFECT P.C.Rx Sw is “On.”
When UTILITY-MIDI screens EFFECT P.C. Rx Sw is “On,” 00H-03H is received if it
operates as the Effect Program Change.
When UTILITY-MIDI screens SCENE P.C. Rx Sw is “On,” MIDI Channel No. FH is received
if it operates as the Scene Change.
If V-LINK function is enable, see “5.V-LINK”.

(*1) If received while VS-2400CD is playing, play back stops,
and then restarts after the scene switched. Never receives while recording.

System Common Messages
●
MIDI Time Code Quarter Frame Messages
MIDI Time Code Quarter Frame Messages can be transmitted while the VS-2400CD is
running (Playing or Recording) if the UTILITY-SYNC screens SYNC MODE is “INT” and
SYNC Gen. is “MTC.”
The transmitted time counts are summed to “SYNC OFF SET TIME” as the project top is
“00:00:00:00.”
The VS-2400CD synchronizes with the time counts which are summed to “SYNC OFFSET
TIME” as the project top is “00:00:00:00” if the SYNC screens SYNC MODE is “EXT.”

Song Position Pointer
The current position is transmitted with the Song Position Pointer Message before the VS-
2400CD starts top run or after the locate operation when UTILITY-SYNC screens SYNC
MODE is “INT” and SYNC Gen. is “MIDIclk” or “SyncTr.”

F7H EOX (End of System Exclusive message)
The VS-2400CD can transfer and receive the internal parameters information using system
exclusive messages, and also can be controlled by the external devices using system
exclusive message.
The VS-2400CD can transmit and receive Universal System Exclusive messages, Data
Request (RQ1) and Data set (DT1) as the System Exclusive Message.
❍
About Model ID
The Model ID of the VS-2400CD is 00H,61H as for Data Request (RQ1) and Data set (DT1).
The VS-2400CD also can receive 00H,61H (VS-2400CD) and 00,36H (VE-7000).
❍
About Device ID
System Exclusive messages are not assigned to any particular MIDI channel. Instead, they
have their own special control parameter called device ID.
The roland system exclusive messages use device IDs to specify multiple VS-2400CD units.
The VS-2400CD sends system exclusive messages using 00H-1FH, and receives the system
exclusive messages whose device ID is same as its device ID and 7FH. the value of the
device ID is the value set on the UTILITY-MIDI screens DEVICE ID minus one.
